Abstract

The invention belongs to the field of underwater manipulators of robot engineering and particularly relates to an underwater electromechanical wrist turning and clamping drive structure. The underwater electromechanical wrist turning and clamping drive structure comprises a wrist turning drive module for achieving an underwater electromechanical wrist turning function, a clamping drive module for achieving an underwater electromechanical wrist clamping function and a joint housing, wherein the wrist turning drive module and the clamping drive module are accommodated in the joint housing respectively. The wrist turning drive module uses gear transmission. The clamping drive module uses ball screw transmission. A second shaft of the wrist turning module is of a hollow structure, a ball screw nut connecting rod for driving a clamp can penetrate through the second shaft of the wrist turning module, and the wrist turning module and the clamping module can be integrated into the joint housing and avoid mutual interference to achieve two functions of an underwater electromechanical arm. The underwater electromechanical wrist turning and clamping drive structure has the advantages of being reliable in performance, compact in structure, easy to maintain and debug and the like.

Description

technical field

[0001] The invention belongs to the field of underwater manipulators in robot engineering, in particular to an underwater electric mechanical wrist-turning clamp driving structure. Background technique

[0002] The underwater manipulator is the main tool for marine development or underwater operations, and it is oriented to the application requirements of future operating AUV (autonomous underwater robot) / ARV (semi-autonomous underwater robot) and small and medium-sized operating ROV (remote control underwater robot) , The underwater manipulator is required to have the characteristics of light weight and low power consumption. The motor drive has the advantages of small volume and weight, low power consumption, high control precision, and the full-sea deep operation can be realized through the pressure compensator. Therefore, the motor-driven underwater manipulator has broad application prospects.

[0003] At present, the underwater electromechanical wrist r...
